Skip to 2:34 to get to the meat of this week's installment of Danja's “Throwback Track Thursday” video series, which includes an unreleased song that the producer of "Bad Girls" did with M.I.A., entitled "Doobie." Danja says the song was recorded in 2007, at the same time as "Bad Girls." ("Bad Girls," though the official single was released in 2012, first emerged on a mixtape at the end of 2010.) M.I.A.'s Matangi LP should be coming out soon, pending Interscope approval.
